Nanotechnology deals with the synthesis of materials and particles at nanoscale with dimensions of 1–100 nm. Biological synthesis of nanoparticles, using microbes and plants, is the most proficient method in terms of ease of handling and reliability. Core objectives of this study were to synthesize metallic nanoparticles using selenium metal salt from citrus fruit extracts, their characterization and evaluation for antimicrobial activities against pathogenic microbes. In methodology, simple green method was implicated using sodium selenite salt solution and citrus fruit extracts of Grapefruit and Lemon as precursors for synthesizing nanoparticles. Brick red color of the solution indicated towards the synthesis of selenium nanoparticles (SeNPs). Nanoparticle’s initial characterization was done by UV–Vis Spectrophotometry and later FTIR analysis and DLS graphs via Zetasizer were obtained for the confirmation of different physical and chemical parameters of the nanoparticles. Different concentrations of SeNPs were used for antimicrobial testing against E. coli, M. luteus, B. subtilis and K. pneumoniae comparative with the standard antibiotic Ciprofloxacin. SeNPs possessed significant antimicrobial activities against all the bacterial pathogens used. Conclusively, SeNPs made from citrus fruits can act as potent antibacterial candidates.

Objective: The study aimed to evaluate the association between disease knowledge and medication adherence in patients with type 2 diabetes mellitus. Methods:A cross-sectional study was conducted for three months, in patients with type 2 diabetes who visited three community pharmacies located in Khobar, Saudi Arabia. Patients' disease knowledge and their adherence to medications were documented using Arabic versions of the Michigan Diabetes Knowledge Test and the General Medication Adherence Scale respectively. Data were analyzed through SPSS version 23. Chi-square test was used to report association of demographics with adherence. Spearman's rank correlation was employed to report the relationship among Hb A1c values, disease knowledge and adherence. Logistic regression model was utilized to report the determinants of medication adherence and their corresponding adjusted odds ratio. Study was approved by concerned ethical committee (IRB-UGS-2019-05-001).Results: A total of 318 patients consented to participate in the study. Mean Hb A1c value was 8.1%. A third of patients (N = 105, 33%) had high adherence and half of patients (N = 162, 50.9%) had disease knowledge between 51% -75%. A significantly weak-tomoderate and positive correlation (r = 0.221, p < 0.01) between medication adherence and disease knowledge was reported. Patients with >50% correct answers in the diabetes knowledge test questionnaire were more likely to be adherent to their medications (AOR 4.46, p < 0.01).Conclusion: Disease knowledge in most patients was average and half of patients had high-to-good adherence. Patients with better knowledge were 4 to 5 times more likely to have high adherence. This highlights the importance of patient education and awareness regarding medication adherence in managing diabetes.

Objective: Patient satisfaction is an indicator for quality of healthcare service and is sometimes linked to patients' willingness to pay. Willingness to pay is an economic method for estimating patient's inclination for a service in monetary terms. This study assessed satisfaction of patients from pharmacist counseling service and estimated their willing to pay for the same. Methods: A month-long survey was conducted in community and hospital pharmacies located in Khobar, Dammam, and Qatif cities of Saudi Arabia, using Arabic version of Patient Satisfaction Feedback (PSF) questionnaire that measured satisfaction with counseling as well as willingness-to-pay. Convenient sampling method was used, and sample size was calculated based on power analysis. Data was analyzed through SPSS version 23. Chi-square (c 2) test and logistic regression analyses were conducted to report associations between variables and, determinants of satisfaction as well as willingness to pay respectively. The study was approved by concerned ethical committee (IRB-2019-05-020). Results: Patients (n = 531) with previous counseling experience were more likely to be satisfied [adjusted odds ratio (AOR) 5.2, p < 0.05]. Patients were more willing to pay if, they had an income above SAR 10,000 i.e., USD 2666.5 (AOR 1.78, p < 0.05), were satisfied with counseling time duration (AOR 4.5) and, were able to get counseling without difficulty (AOR 2.1, p < 0.05). Patients were more likely to be satisfied and were willing to pay if, they received required knowledge/information completely (AOR 2.5, 3.7, and p < 0.05) and found pharmacist helpful (AOR 1, 4.5, and p < 0.05). Most patients (43.9%) were satisfied with pharmacist counseling and average satisfaction rating was 7.87 ± 1.99/10.

Purpose The study aimed to translate and validate the Arabic version of General Medication Adherence Scale (GMAS) in Saudi patients with chronic diseases. Methods A multi-center cross sectional study was conducted for a month in out-patient wards of hospitals in Khobar, Dammam, Makkah, and Madinah, Saudi Arabia. Patients were randomly selected from a registered patient pools at hospitals and the item-subject ratio was kept at 1:20. The tool was assessed for factorial, construct, convergent, known group and predictive validities as well as, reliability and internal consistency of scale were also evaluated. Sensitivity, specificity, and accuracy were also evaluated. Data were analyzed using SPSS v24 and MedCalc v19.2. The study was approved by concerned ethics committees (IRB-129-25/6/1439) and (IRB-2019-05-002). Results A total of 282 responses were received. The values for normed fit index (NFI), comparative fit index (CFI), Tucker Lewis index (TLI) and incremental fit index (IFI) were 0.960, 0.979, 0.954 and 0.980. All values were >0.95. The value for root mean square error of approximation (RMSEA) was 0.059, i.e., <0.06. Hence, factorial validity was established. The average factor loading of the scale was 0.725, i.e., >0.7, that established convergent validity. Known group validity was established by obtaining significant p-value <0.05, for the associations based on hypotheses. Cronbach’s α was 0.865, i.e., >0.7. Predictive validity was established by evaluating odds ratios (OR) of demographic factors with adherence score using logistic regression. Sensitivity was 78.16%, specificity was 76.85% and, accuracy of the tool was 77.66%, i.e., >70%. Conclusion The Arabic version of GMAS achieved all required statistical parameters and was validated in Saudi patients with chronic diseases.
